Indications for Use
ELITONE is a non-implanted muscle stimulator designed to treat stress urinary incontinence in women. It applies stimulation to the pelvic floor muscles and surrounding tissues.
Device Story
ELITONE is a wearable, battery-powered muscle stimulator for treating stress urinary incontinence in women. It uses a disposable, adhesive hydrogel electrode applied to the perineal region to deliver electrical muscle stimulation (EMS) to pelvic floor muscles. The device is operated by the patient via a small ABS plastic control unit with two pushbuttons to adjust intensity and manage treatment sessions. The device delivers a symmetric, amplitude-modulated (2000Hz) sinusoidal waveform, alternating between 50Hz (for muscle strengthening) and 10Hz (to calm detrusor activity). Each 20-minute session is automated. The device is intended for home use, allowing patients to self-administer treatment 3-5 times per week. By strengthening pelvic floor muscles, the device aims to reduce incontinence episodes and improve quality of life. Healthcare providers use the device output to support clinical management of stress incontinence.
Clinical Evidence
Clinical evidence includes a 20-subject prospective study of women with mild-moderate stress incontinence using Elitone for 6 weeks. Results showed clinically significant improvements in incontinence episodes, pad usage, and quality of life. No adverse events occurred. Additionally, a literature review supported the safety/efficacy of perineal-applied EMS. Usability testing with 15 subjects confirmed that users could correctly self-select based on labeling and safely operate the device.
Indicated for women with stress urinary incontinence. Contraindicated for women with urge urinary incontinence.

#### Device Description:
The Elitone Device provides electrical muscle stimulation (commonly called EMS or E-stim) to treat stress urinary incontinence. Stimulation is delivered to the pelvic floor muscles and surrounding structures through a disposable cutaneous electrode applied to the perineal region. One end of the thin, flexible electrode is positioned proximate the pubis and the other end is positioned proximate the ischial tuberosity. Mildly adhesive and electrically conductive hydrogel portions of each electrode attach the electrode to the perineal tissues and allow comfortable transfer of electrical stimulation through the pelvic floor. The stimulation is controlled by a battery powered, wearable control unit. The housing of the control unit is approximately 55mm x 45mm x 10mm and made of ABS plastic. It includes two pushbuttons that allow the user to increment the voltage (i.e. intensity), and to start, pause and stop device operation. The stimulation utilizes a symmetric, amplitude modulated (2000Hz), sinusoidal waveform. The output intensity operates over a range of levels (0-35) that approximately correspond to a 0-30mA RMS current. The stimulation frequency alternates between a higher frequency portion (50Hz) and a lower frequency portion (10Hz). Higher frequency stimulation is typically used to encourage muscle contraction and strengthening of the pelvic floor muscles. Lower frequency stimulation is typically used to calm detrusor muscle activity, decreasing symptoms of urgency type incontinence. Each treatment session lasts 20 minutes, after which the device turns off automatically. Women are recommended to use the device 3-5 times per week.
#### Intended Use:
ELITONE is a non-implanted muscle stimulator designed to treat stress urinary incontinence in women. It applies stimulation to the pelvic floor muscles and surrounding tissues.
#### Comparison to the Predicate Device:
The table below provides comparisons of the Elitone Device to the predicate Innovo device. The primary difference is the application site of the electrical stimulation. The Elitone Device delivers stimulation via
{4}------------------------------------------------
a cutaneous electrode placed on the perineal tissues whereas the predicate delivers stimulation via cutaneous electrodes placed on the buttocks and thighs. This technological difference does not raise different questions of safety or efficacy. Further, acceptable methods exist to characterize the technological differences and results from those methods demonstrated substantial equivalence of the Elitone Device.

### Testing Summary:
The following performance testing was provided in support a substantial equivalence determination. The Elitone Device passed all testing.
- Software Verification and Validation Testing The software for the device was considered to be a ● "moderate" level of concern. Verification and validation testing was completed as recommended by FDA guidance pertaining to medical device software.
- . Electrical Safety and Electromagnetic Compatibility (EMC) Testing – Testing was completed by external labs per IEC 60601-1 and IEC 60601-2-10 standards for safety and IEC 60601-1-2 standard for EMC.
{5}------------------------------------------------
- Other Performance Testing - Performance of the electrode component was assessed by measuring its impedance, its adhesiveness and its current dispersion. Comparisons were made to legally marketed EMS electrodes.
- Biocompatibility Assessment – A biocompatibility evaluation was completed in accordance with the ISO 10993-1 standard. The electrode is considered tissue contacting for a duration of less than 24 hours. The materials, manufacturing processes and use application are the same as those of legally marketed electrodes. Accordingly, no new biocompatibility testing was needed to demonstrate safety and efficacy.
- . Clinical Literature Evaluation – A literature review was conducted to demonstrate the safety and efficacy of perineal-applied EMS in the treatment of female urinary incontinence. Articles were reviewed to assess their relevance to the performance and safety of the Elitone device.
- . Clinical Testing – Results from a 20 subject study were submitted. Subjects were with mild-moderate predominant stress incontinence who self-administered treatment with Elitone for 6-weeks. Key findings includes clinically significant improvements in incontinence episodes, pad usage and quality of life measures. There were no adverse events that resulted in injury or required medical treatment.
- . Usability Testing – 15 subjects participated in a human factors / usability study to assess the device's suitability for safe over-the-counter use. Key finds included: (1) participants with diversity in age, education and familiarity with incontinence were able to self-select as appropriate users of the Elitone device based on the package label, (2) participants were able to understand the instructions for use and a qualified healthcare professional (observer) verified that they correctly self-identified as candidates based on the indications for use and contraindications, and (3) participants were able to apply treatment safely and correctly.
#### Risk Management Summary:
The Elitone Device has been designed according to Elidah's internal procedures with traceability between the design inputs, design outputs, verification and validation activities. The Elitone Device has been evaluated for risks according to Elidah's internal procedures based on ISO 14971. The risks associated with the Elitone Device were individually and collectively assessed, and the risk/benefit analysis was acceptable.
#### Conclusion:
The non-clinical data support the safety of the device, and the software verification and validation demonstrates that Elitone performs as intended in the specified use conditions. The clinical literature evaluation, as well as the technological comparison to the predicate device, supports the use of transcutaneous electrical stimulation as an effective treatment of stress urinary incontinence in women. The clinical study supports the effectiveness of the device and confirms the low-risk nature of EMS devices. The usability study was designed to ensure that potential users could self-identify as having stress urinary incontinence (allowing for the use of the product) while also self-identify as not having urge urinary incontinence (excluding them from use). The verbiage used in the product labeling was found to be appropriate for this kind of self-identification in a general population of women. The data included within this submission supports Elitone as a safe and OTC treatment for stress urinary incontinence in women.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
